SSG: Static-site generation

Runs once at build-time - reused for each request

SSR: Server-side rendering

Runs on every request - fetch data before sending page to client

CSR: Client-side rendering

Runs on every request - load page first and fetch data on client-side (loading... => data)

ISR: Incremental Static Regeneration

SSG and SSR combined - update data after a certain revalidation time (7 seconds)
